The disk I is constructed o'nfthe outer side with a central hub, is,andis held in place4 by an outer plate,'D1, extending at its edgesl astthe periphery of the disk, in order to hear firmly 'against the outerface of the bod plate D, to which it is firmly secured byliorizontalscrews, d, the two platesA D forming in effect-.ay rigidmframe within4which the plate I is seated.
